Xpdf is an open source viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities.

Xpdf is designed to be small and efficient. It can use Type 1, TrueType, or standard X fonts.

PeasyScale can resize single JPEGs or entire folders. In either case, the new images are stored in a subfolder named PEASYSCALE :
Peasyscale
This is AutoAdjustPhoto_GUI-2.0 ---> a front end for the aaphoto command line tool :
AAphoto resizer

scale2pics /usr/share/backgrounds /root/testpics/ 30 20 85 jpg
(the targetfolder may not exist yet)
This will do:
- create a folder /root/testpics/
- create in this folder scaled jpg-files with a maximum size of 30x20 pixel, with 85% quality from all pictures in /usr/share/backgrounds :
scale2pics

Shrink is a very simple application that will allow you to reduce the size of a photo to either 640x480, 800x600 or 1024x768.
